Gender: Male First person: I (polite/soft) A member of the Rescue Corps to which the protagonist belongs. He is characterized by his large build, wide green eyes, and gray, spring-like hair. He hails from the planet Karat. As a member of the Rescue Corps, he is the protagonist's senior colleague. His official role is Communications Operator, primarily responsible for relaying information to the team. However, he also handles various chores such as maintaining the S.S. Shepherd and caring for rescued castaways. He has a gentle personality and is polite and soft-spoken, even using respectful language with his junior, the protagonist. On the other hand, he is the biggest glutton on the team; he was scolded by Shepherd for overeating on the first night. He also has a bit of a cowardly side, though not as much as Captain Shepherd, such as screaming when entering underground caves. He is quite diligent and often advises team members to check their rescue progress. When he suggested this to Dingo, who was exhausted from camping out, Dingo was exasperated, calling him a "demon." Ultimately, for the current Rescue Corps—which is full of well-meaning but somewhat flighty members—he is the unsung hero who keeps everything running behind the scenes. His dexterity and flexibility were apparently cultivated through working various part-time jobs during his days as a struggling student. In addition to tinkering with machinery since childhood, he has continued to use a radio inherited from his grandfather as a "treasure," replacing parts as needed. By the time he joined the corps, he had already acquired the skills to work as a professional radio operator. He seems to continue tinkering with machines even now as a form of mental training. His name is likely derived from the Border Collie, a breed of herding dog originating in Britain. As a side note, while the Border Collie is a herding dog, it is also a breed that excels as a disaster rescue dog (though less famous in that role than the German Shepherd), making it a fitting name for the protagonist's senior and operator.
